What Starter Pack basically said.
You make a request in the
Content Revision Promotion Thread, and if no one comes there and gives any input, then that's where you personally contact staff members on their message walls/forum profiles, and if they're interested, maybe they'll go there and take a look. The areas of responsibilities for Content Moderators are different, so you should most likely call a Thread Moderator because your interests would be mostly aligned with their responsibilities if you're making a content revision thread, but then again, I don't know what thread you are referring to specifically because you were so vague about it.
